		<h3><a href="#">Notes</a></h3>
		<div>
			<ul>
				<li>In <span class="version">v2.11</span>, the pager now stores any object returned by the `ajaxProcessing` function in `table.config.pager.ajaxData` (see the ajaxProcessing section below for more details).</li>
				<li>In <span class="version updated">v2.10</span>, the <code>ajaxProcessing</code> function was updated to only require a total number of rows to be returned, also instead of returning an array of table rows, you can build the table yourself and just return the jQuery object containing those rows. The addon triggers an update.</li>
				<li><code>{filterList:fcol}</code> was added to the <code>ajaxUrl</code> in version 2.6.</li>
				<li><code>{sortList:col}</code> was added to the <code>ajaxUrl</code> in version 2.4.5.</li>
				<li>This update to the pager plugin that interacts with a database via ajax was added in version 2.0.32 and can be applied to the original tablesorter.</li>
				<li>The <code>ajaxUrl</code> and <code>ajaxProcessing</code> function are both required options for this interaction to work properly.</li>
				<li>The <code>ajaxUrl</code> contains a replaceable string to send the requested page (<code>{page}</code>), block size (<code>{size}</code>) or sort order (<code>{sortList:name}</code>).</li>
				<li>The table header and footer text will be updated to match the JSON "header column #" text; but there is an issue with the table rendering improperly if the number of columns in the HTML and the number of columns in the JSON don't match.</li>
				<li><strong>Limitations of this demo</strong>:
					<ul>
						<li>This demo will not work when viewing it locally (except in Firefox) due to communication restrictions between the browser and your desktop.</li>
						<li>The record size is limited to 25 records because this demo is not interacting with an actual database, but with four JSON files containing 25 records each.</li>
						<li>Sorting of columns is disabled in this demo because no table data is cached when <code>serverSideSorting</code> is enabled. <del>Sorting of columns is enabled in this demo by setting the <code>serverSideSorting</code> option to <code>false</code> after initialization. It only sorts the current table contents because there is no server to return sorted data</del>.</li>
						<li>The filters will only update the "Current Ajax url" because again, we're just working with JSON files here.</li>
					</ul>
				</li>
			</ul>
			<p class="small">* If you have a different JSON format and need help with the processing code, please ask the question on <a href="http://stackoverflow.com/questions/tagged/tablesorter">StackOverflow</a> or message me directly (gmail; wowmotty). Please don't open an issue for help with code.</p>
		</div>

		<h3><a href="#">ajaxProcessing</a></h3>
		<div>
			The <code>ajaxProcessing</code> function is needed to convert your custom JSON format into an array usable by the pager plugin (modified in 2.1.3)<br>
			<br>
			So, given this custom JSON format (this is only an example):
			<pre class="prettyprint lang-javascript">{
  "total_rows": 80,

  "headers" : [
    "ID", "Name", "Country Code", "District", "Population"
  ],

  "rows" : [{
    "ID": 1,
    "Name": "Kabul",
    "CountryCode": "AFG",
    "District": "Kabol",
    "Population": 1780000
  }, {
    "ID": 2,
    "Name": "Qandahar",
    "CountryCode": "AFG",
    "District": "Qandahar",
    "Population": 237500
  }, {
    ...
  }, {
    "ID": 25,
    "Name": "Haarlemmermeer",
    "CountryCode": "NLD",
    "District": "Noord-Holland",
    "Population": 110722
  }]
}</pre>
		<h3>OBJECT returned</h3>
		<ul>
			<li>In <span class="version">v2.11</span>, the <code>ajaxProcessing</code> can just return the above object directly (<strong>or don't even bother setting an <code>ajaxProcessing</code> function</strong>).
				So, if an object is returned by the <code>ajaxProcessing</code> function, the data is stored in <code>table.config.pager.ajaxData</code>:
				<ul>
					<li>The object should contain attributes for <code>total</code> (numeric), <code>headers</code> (array) and <code>rows</code> (array of arrays).</li>
					<li>A replacement <code>output</code> option can also be loaded via this method and must be included in the <code>output</code> attribute (i.e. <code>ajaxData.output</code>).</li>
					<li>Additional attributes are also available to the output display by using the attribute key wrapped in curly brackets (e.g. <code>{extra}</code> from <code>ajaxData.extra</code>).</li>
					<li>Additional attributes can also be objects or arrays and can be accessed via the output string as <code>{extra:0}</code> (for arrays) or <code>{extra:key}</code> for objects.</li>
					<li>The page number is processed first, so it would be possible to use this string <code>{extra:{page}}</code> (<code>{page}</code> is a one-based index), or if you need a different value use <code>{page+1}</code> (zero-based index plus any number), or <code>{page-1}</code> (zero-based index minus any number).</li>
					<li>For more details, please see <a href="https://github.com/Mottie/tablesorter/issues/326">issue #326</a>.</li>
				</ul>
			</li>
		</ul>
		<h3>ARRAY returned</h3>
		<ul>
			<li>The <code>ajaxProcessing</code> function can return the data in the following format <code>[ total, rows, headers (optional) ]</code>,
				<br>or in version 2.9+ <code>[ rows, total, headers (optional) ]</code>,
				<br>or in <span class="version">v2.10</span>, return a jQuery object within the array <code>[ total, $rows ]</code>, or just <code>[ total ]</code>:
					<pre class="prettyprint lang-javascript">[
  // total # rows contained in the database
  80,
  // row data: array of arrays; each internal array has the table cell data for that row
  [
    [ 1, "Kabul", "AFG", "Kabol", 1780000 ],                 // [ "row1cell1", "row1cell2", ... "row1cellN" ],
    [ 2, "Qandahar", "AFG", "Qandahar", 237500 ],            // [ "row2cell1", "row2cell2", ... "row2cellN" ],
     ...
    [ 25, "Haarlemmermeer", "NLD", "Noord-Holland", 110722 ] // [ "rowNcell1", "rowNcell2", ... "rowNcellN" ]
  ],
  [ "ID", "Name", "Country Code", "District", "Population" ] // [ "Header1", "Header2", ... "HeaderN" ] (optional)
]</pre></li>
			</ul>
